my near 3 year old daughter is great with her potty. She sometimes wets the bed at night but I am not concerned with that because it is not all the time. She won't have a BM in the potty. She hides and does it in her pants. I don't know what to do, I have bribed her, I have gotten upset I even tried the positive side where I praise everytime she pees on the potty. But nothing is making her want to have a BM on the potty please help me.
